Of the eight known nests in Manhattan, here's their status this week (changes in italics)...

5th Avenue, nest failure. NYC Audubon is coordinating with the building to retrieve the eggs for testing when they do their window washing.

888 Seventh Avenue, uncertain.

St. John the Divine, two eyasses visible.

Highbridge Park, nest abandoned, two eyasses presumed to have died at about two weeks of age, reasons unkown.Robert Schmunk, James O'Brien and I have all spent time up at the nest over the last week and it has been abandoned. James O'Brien discovered the pair mating this weekend, so we've all agreed the nest has failed.

Inwood Hill Park, two or three eyasses depending on reporters. Nest is now surrounded by green leaves making it difficult to observe.

South Riverside Park,. Parents have built a new nest. It is uncertain if they will lay eggs this year, or wait until next spring. Toxicology reports due for the second and third eyasses soon.

Houston Street, three eyasses.

Shepard Hall, City College, nest is too difficult to observe to be sure. Update 5/28: I had confused a note from James O'Brien about where copulation had occurred. It was at Highbridge, not City College. So, behavior still makes the nest look active with hatched eggs, however there has yet to be a sighting of an eyas.
